Abstract
PURPOSE: To stably control the water supply rate by imparting a throttling function to a water supply rate regulating valve.
CONSTITUTION: A water supply pipe 2 leading to a vapor generator 1 is equipped with a water supply pump 3, a flow regulating valve 4 and a flow meter 5, and the flow rate signals 6 from the flow meter 5 are compared with a preset flow rate value 7 so that difference signals are fed to a flow rate control system 8 to the regulating valve 4. A difference pressure meter 9 for metering the pressure difference P between upstream and downstream of the regulating valve 4. The resultant difference pressure signals 10 are compared with the signals 13, which are produced by adding the biase signals 12 for eliminating the negative resistance to a preset pressure difference level 11, and are then fed to a first pump speed control system 14. The resultant output is compared with the signals of a pump speed detector 15 so that the resultant difference signals are fed to a second pump speed control system 16 to control the speed of the water supply pump 3. Thus, the throttling function is imparted to the regulating valve 4 so as to stabilize the water supply flow rate.
